Aero8Tuner is the successor of my famous Aero Tuner (for Windows 7) and White Windows (for Windows 8 ). It allows you to change all settings of DWM/Aero at Windows 8 RTM+.With Aero8Tuner you will able:

to set any color of windows.

to disable windows coloring. If you will enable this undocumented feature, the color of windows borders in Windows 8 will be always white.

to change color balance (affects the intensity).

to force High Contrast mode for regular themes. The blurless buggy Aero transparency will be appeared in this case.
